Lecture II
To evaluate this fact properly, we must know something of the close connection between all the excretory processes and those activities which include soul and spirit. The constructive processes, the vital processes proper, are the foundation of the mere unconscious. Corresponding to the conscious soul and organic functions of our waking hours, are always processes of excretion. Even our thinking does not correspond to constructive cerebral processes, but to processes of excretion, i.e. destruction. And night sweats are an excretory phenomenon which should be concurrent with a spirit and soul activity in normal life. But as the upper and lower spheres are not in correct interaction with one another, the excretory process accumulates and then takes place at night, when the organism is relieved from spirit and soul activity.
